this is not a compiler issue. Apparently you have to build the modules
and the kernel with the same version of the compiler, which is now
5.4.x. We usually don't update the dependencies packages, the symlinks
stay the same.

Title:
Cannot build nvidia driver via dkms because compiler doesn't match
kernel

Bug description:
The kernel installed with 16.04 was built with gcc 5.3.1, but the
default compiler installed is 5.4.0 - as such, DKMS refuses to build
the nvidia video card driver due to the mismatch. Either build the
kernel with the shipping compiler or ship the compiler that was used
to build the kernel.
